Abstract—A new decentralized fuzzy adaptive controller for a class of large scale affine nonlinear systems is presented in this paper. The proposed controllers are mainly based on fuzzy concepts. Stability of closed-loop system, convergence of the tracking error to zero and avoidance of chattering in adaptation laws are guaranteed in this controller design procedure. Simulation results have very promising performance.

Index Terms—Intelligent adaptive control, non-affine nonlinear systems, large scale system, fuzzy system.
